The director said he did not believe the recent leak of a “private security company document,” apparently alleging Russian claims that they had compromising information on Mr. Trump, came from within the U.S. intelligence community.

Asked if she still believes there’s a chance it came from the intelligence community, Ms. Conway said: “What I believe doesn’t matter.”

“What matters is that the president-elect had a briefing by the four top intelligence officers in our nation last week,” she said. “Then, no sooner do they have it than people are leaking information.”

Mr. Clapper also said he emphasized the document was not a U.S. intelligence product and that it hasn’t made any judgment that the information within is reliable.
